A clown seen hanging onto the back of a moving Detroit bus in a YouTube video is under police investigation.

With bright, bushy orange hair, a red nose and what appears to be a white lab coat, the clown can be seen gripping onto the rear of the Detroit Department of Transportation bus as it drives down a street.

The 9-second video posted Oct. 8 on YouTube had drawn more than 12,500 views by Tuesday morning; the same video posted on Facebook had more than 623,000 views.

WARNING: It has graphic language.

The transportation department and a local TV station sent the video link to Detroit police, and its criminal investigations bureau is looking into it, said officer Jennifer Moreno. She said the clown may have committed a civil infraction by riding on the back of the moving vehicle.

The video was posted on YouTube by username 23Pacman23 and on Facebook by username Detwan Hall. Another video posted the same day on Hall's page shows what appears to be the same clown looking out of the back seat of a car.

A weird trend, creepy clowns have appeared — and been accused of crimes — across the metro area and in other parts of the country in recent weeks.
